I like JST connectors for internal connectors, but a PH header is only 1.1 mm narrower than the barrel jack. I can get power adapters terminating in a barrel plug from anywhere or DIY a barrel plug-to-banana cable to use with a bench supply. PH connectors I really only see with batteries...

On making it smaller: two-sided assembly, 6 layers, and possibly separating the power connector to a free hanging inline receptacle could make the board a lot narrower. Definitely some tradeoffs to do that though.

I would like the PH headers !  As I said, the power cable wouldn't be something I would ever disconnect, so soldering it would be just fine.

What kind of cable would you recommend between the probe and the scope ?

Best Regards,
